How to replace the fuel pressure regulator on Cadillac Seville?

A proper replacement procedure for the Fuel Pressure Regulator begins by draining fuel pressure through proper servicing of the quick-connect metal collars. The Fuel Pressure Regulator needs cleaning of all dust before disconnecting its vacuum line. Use a shop towel to absorb flowing fuel when you remove the retainer clip before lifting then twisting off the Fuel Pressure Regulator from its attachment to the Fuel Rail. Start by taking out both the lower o-ring along with the regulator assembly filter and the upper o-ring and finally remove the back up ring. You should cap the Fuel Pressure Regulator housing to stop foreign substances from accessing the fuel system. New o-rings need to be applied for installation when the regulator is unchanged. The rings should receive light lubrication with clean engine oil. The first step involves placing the upper o-ring while moving to the filter and afterward setting the lower o-ring in position. Fasten the retainer clip on the Fuel Pressure Regulator then return the vacuum line. Reinstall the negative Battery Cable while checking for fuel leaks by using the following on-off-off sequence that starts with on for 2 seconds before moving to off for 10 seconds and finishing with another on position. Place the fuel injector sight shield as the last step.
